GAS-BURNER FOR FU RNACES.

SPECIFICATION forming part of Letters Patent No. 670,979, dated April 2, 1901.

Application filed November 14, 1900. Serial No. 36,507. (No modeL] To all whom it may concern:

Be it known that I, CHARLES F. ALLEN, a citizen of the United States, residing at Massillon, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in GasBurners for Furnaces and Kindred Heaters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will 1o enable others skilled in the art to which it appertains to make and use the same.

This invention has for one object the provision of a burner for consu ming natural and artificial gas and adapted to be fitted to a coal-burning furnace or like heater Without necessitating the disturbance of the grate or other parts of' the fire-pot, which would preclude the use of solid fuel in the furnace, and which is adjustable, so as to be fitted to difzo ferent-sized furnaces Within certain limits, thereby avoiding the expense of a burner of given size for each size of furnace.

A further object of the invention is to provide a burner which Will not give off any free carbon and apply the flame so as to utilize a maximum amount of caloric for effective heating and which can be readily fitted to any make of furnace.

For a full description of the invention and 3o the merits thereof and also to acquire a knowledge of the details of construction of' the means for effecting the result reference is to be had to the following description and drawings hereto attached.

While the essential and characteristic features of the invention are necessarily susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which-- Figure l is a perspective view of a burner embodying the invention. Fig. 2 is a top plan View, the sections being separated at one end. Fig. 3 is a transverse section about on the line X X of Fig. 2, Fig. a is a perspective view of a burner-head inverted. Fig. 5 is a perspective view of the cap of the burner-head as seen from the inner side. Fig. 6 is a perspective View of the pivotal ends of the burnersections separated to show more clearly the pivot-joint.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The burner may be of any outline conformable to its special use; but for general purposes it is preferably of circular form and composed of sections so related as to admit of the burner being expanded or contracted to fit furnaces of different sizes Within certain limits. The sections are by preference semicircular in form and are provided at corresponding ends With offstanding lugs l, which are adapted to overlap and receive a pivotfastening 2, passing through openings in the lugs in `coincident relation. The burnersec tions 3 are hollow and closed at their ends and may have any cross-sectional form,which, as illustrated, is approximately square. A valve 4L is fitted to the free end of each section 3 to control the infioW of gas thereto from the service-pipe or other source of supply. A series of nipples 5 are fitted in openings formed in the top side of the respective sections and are spaced apart any required distance and are centrally perforated for the escape of gas in a jet into the respective burner-heads. These nipples 5 are preferably of brass and have screw-thread connection with the body, so as to be detached therefrom when required for any purpose.

The burner-heads 6 are located at intervals burner-heads are preferably composed 0f similar parts 9 and 10, secured together by bolts 11 or kindred fastenings. The inner faces or sides of the paris 9 and 10 are recessed to form a chamber 12 to receive the gaseous mixture, which is consumed at the flame-openings 7 when the burner is in operation. The part 9 of the burner-head constitutes a cap-plate, and the flange 13, surrounding its outer edge portion, forms a recess upon its inner side and is provided with a series of notches in its outer portion correspending with the straight edge of the burnerhead to forni the dame-openings 7 when the parts 9 and 1() are united. The spacing-lugs 8 are by preference formed with the lower part 10 of the burner-head. So far as the spirit of the invention is involved the notches forming the flame-openings 7 may be provided in either part of the burner-head. A tubular stem 14 is formed with or applied to the burner-head and is by preference cast with the part 10 and has slots or openings 15 in its sides for the admission of air to commingle with the gas on its way to the burnerhead to be consumed. The tubular stem 14 is centrally disposed with reference to the length of the burner-head and is located adjacent to the inner edge thereof, whereby the best results are attained in the distribution of the gaseous mixture throughout the burnerhead, so as to insure uniform tongues or jets of Haine at the openings 7. The stems 14 are fitted to the respective nipples 5, preferably by a slip-joint, so as to admit of the ready detachment of the burner-heads for cleaning or other purpose.

A sleeve 16 surrounds the tubular stem 14 of each burner-head and is of frusto-conical form, the lower edge being formed with a series of notches 17 for the admission of air to mix with the gas. The upper end of the sleeve 16 fits close to the sides of the stem 14 and comes against the lower side of the burnerhead in such a manner as to prevent the escape of gas at this point. The provision of the sleeve 16 insures a heating of the air prior to its admixture with the gas and results in intensifying the heat of the jets of flame, besides promoting combustion. The sleeve by reason of its lai-ing formation obtains sufficient bearing at its lower end upon the body of the burner to enable it to brace the burnerhead and hold it in proper position.

By roundingthe innercorners of the burnerheads they are enabled to come close together at their ends and to conform to the circular outline of the burner, and, moreover, the ends of the chambers 12 conforming to the terminal curvature of the burners, the gaseous mixture is given direction to the terminal flame-openings and a nearly uniform pressure secured throughout the chamber 12, whereby the tongues or jets of flame are about equal. When the free ends of the sections 3 of the body of the burner are together, as shown in Fig. 1, the burner can be fitted to the smallest-size furnace,and when applying the burner to the next larger size furnace the ends of the sections are spread, as in Fig. 2, and for a furnace of next larger size the ends are separated for agreater distance.v It will thus be seen that the burner is adjustable within certain limits for different-sized furnaces. By having the dame-openings 7 at theouteredges of the burnerheads the flame is directed against the sides of the furnace and the caloric utilized to the best possible advantage for heating, whether the system be hot air, steam, or Water. l

Having thus described the invention, what is claimed as new is- 1. A gas-burner for furnaces and heaters of like character composed of sections pivotally connected at one end and adapted to be separated at their opposite ends to admit of the burner being made larger or smaller as required, substantially as set forth.

2. A gas-burner for furnaces and analogous heaters composed of similar sections having offstanding lugs at one end pivotally connected and adapted to be separated at their opposite ends to vary the size of the burner, independent means for admitting gas to each section, and a series of burner-heads fitted to the respective sections, substantially as set forth.

3. A burner comprising an approximately circular gas-distributing body, a series of oblong and attened ,burner-heads having their inner corners rounded and their outer edges straight and formed with a series of flameopenings and arranged in a circle with their ends'adjacent or in opposition, and tubular connections between the gas distributing body and the respective burner-heads and attached to the latter midway of their ends, substantially as set forth.

4. In a burner of the character described, and in combination with a hollow gas-distributing body, burner-heads arranged in a circle and loosely fitted to said body and having flame-openings in their outer edges and provided with spacing lugs, substantially as specified.

5. In a burner of the character described, and in combination with the hollow gas-distributing body, a burner-head having a tubular stem formed in its sides with openings, and a sleeve loosely fitted upon said stem and notched in its lower edge for the admission of air and resting upon the body of the burner and adapted to serve as a brace for the burnerhead, substantially as specified.

6. The herein-described gas-burner for furnaces and kindred heaters, composed of an adjustable sectional hollow body, gas-controlling means tted to each section, nipples applied to the top side `of the said sections, burner-heads of oblong and flattened form arranged in a circle and having their outer edges straight and their inner corners made IOO IOS
